Hmmm, I can imagine BLF getting into custom mixed phosphor creation.

I recall when the original single-phosphor “office white” fluorescents got driven out by “triple phosphor” high color rendering fluorescent tubes.
Triple phosphor lamps had another advantage, as some phosphors have a long decay time so kept puttiing out light when the AC power 60 cycle went through its zero point or the AC power flickered briefly.
Yeah, I’m a dinosaur.
